This invention pertains to a window adjustment, and more particularly to an adjustment that permits the complete removal of the window from a window frame.

The primary object of the present invention resides in a window adjustment that when assembled in a window frame, will permit the expedient removal of the window therefrom.

Another object of the invention resides in a window adjustment that may be assembled in any present or new construction.

A further object of the invention resides in the convenient use of a screwdriver for removing a Window' from a frame.

A still further object is taught in that. with the present adjustment, allowance for normal wear, expansion and contraction of the window and the frame, may be accommodated for; thus convenient operation of the window at all times being extant.

A further object of the present invention is shown in an adj ustment', durable and economical of manufacture.

Other objects, will become apparent as the specification proceeds, and more particularly' when considered in conjunction with the accompanying drawing containing the several views in which:-

Fig. 1 is an elevational view ofv a. window frame, showing my adjustment therein, in dotted lines,

Fig. 2. is a transverse sectional View of the window frame showing the adjustment, taken along line 2 2 of Fig. 1,

Fig. 3 is another detail sectional view of the adjustment taken along line 3 3 of Fig. 2.

Fig. 4. is also. a detail sectional view oi the adjustment taken along line. 4 4 of Fig. 3,

Fig. 5 is a detail sectional view showing. the manner in which the adjustment is secured to a conventional window slide channel, and

Fig. 6 is a perspective view of the adjustment alone.

The adjustment is shown in Fig. 1 of the drawing mounted in a conventional window frame generally indicated by the numeral 2, and having upper and lower window sashes 4 and 6 respectively. The sashes are adapted to slide in a pair of spaced apart metal window slide channels. For purposes of illustration and adaptation to my adjustment I show only one of said slide channels indicated by the numeral 8, containing beads I and I2 cooperating with the grooves or raceways for raising or lowering the sashes.

The adjustments generally indicated as at I4 are mounted to the slide channel 8, by screws I6 in the filler strip I8. Similarly the adjustment is anchored to the window frame by screws passing thru holes 20 in the front flange 22 of the adjustment assemblyshown in Fig. 6 of the drawing. The adjustment assemblies are mounted unilaterally on one slide channel only, and in multiple arrangement to comp-lement the size or length of the window.

The pertinent details of construction of the adjustment proper consist in a body portion having the base 24, front flange 22, and rear turned flange 26. A slidingI arm, generally indicated as at 28, is formed oftwo sections 38 and 32 having turned edges 34 for retaining the ller strip I8 and similarly turned portions 36 of greater length adapted to slide thru an aperture 38 at one side of ange 22 of the body portion.

A guide channel 40 is aligned with the aperture 38 adapted to guide the sliding arm 28 as it is moved by means to be presently described. The guide channel 40 is formed channelwise as shown in Fig. 3, of the drawing, and has a foot flange 4 2, with tabs 44 passed thru suitable apertures in the base flange 24 and crimped for rigid assembly thereto.

Mounted at the opposite end of the sliding arm 2'8, and similarly in the front ange 22 is an adjusting means adapted to advance or withdraw the sliding arm za within the body portion, as

resist turning with the screw 46.

earlier referred to. The slotted head screw 46 j'ournalled in the front and rear flanges 22 and 26, has a square nut 48 threaded thereon. In assembly the nutis positioned so that its at portion will bear against the base 24 and thus In this manner the nut 48 will traverse the length of the screw 4,6 as it is turned. An actuator arm 50 is slotted as at 56ato grip or embrace the nut 48, and move therewith. The actuator arm is pivoted as at 54 in the base 24 and its opposite end 56 adapted to t into an aperture 58 formed in the portion 36 of the sliding arm 28.

In operation it can be appreciated by reference to Fig. 6, of the drawing, that by rotation of the screw 46, available for use thru the hole 60 in the trim or garnish moulding 62, the nut 48 will move along the length of the screw 46 and pivot the actuator arm 50 and impart a linear travel of the sliding arm 28 and hence to the window slide channels and sashes for adjustment.

It can thus be appreciated that in the foregoing description a useful, eiiicient, window adjustment has been accomplished.

While I have shown and described the principal embodiment of my invention, it is obvious that certain alterations and modifications may be made by those skilled in the art, without departing from the spirit and scope of the invention, and I wish to avail myself of any and all that might come within the scope of the appended claims.

I claim:
